Be it known that we, ALBERT J. Smnnx and LEON STONE, citizens of the United States of America, residing at Paris, in the county of Monroe and State of Missouri, have invented new and useful Improvements in Gas-Generators, of which the following is a. Specification.

This invention is an improved gas enerator adapted to convert kerosene, crude oil, or other liquid hydrocarbon into an explosive gas for use in an engine of the explosive type and also adapted for use in other connections, and the same consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In thc accompanying drawings,-Figure 1 is a side elevation of a gas generator con- Structed in accordance vwith this invention, a

Ortion of the carbureter conduit being roken away to disclose a portion of the exterior of the heating conduit. Fig. 2 is a sectional view of the same on a plane at richt angles to Fig. 1. Fig. 3 is a detail top p an View of the cup intowhich the li( uid hydrocarbon is fed. Fig. 4 is a detall sectional view of the heating conduit.

In accordance with this invention we provide a heating conduit through which passes a suitable heating medium1 such,'for instance, as the heated air and spent gases exhausted from an explosion engine. 'e first describe an embodiment of such heating conduit.

A tube lof suitable length and diameter is exteriorly spirally threaded, as at 2, such Spiral thread extending from n carly the upper end thereof to within a Suitable distance of the lower end thereof. The Said tube is upright, and said spiral thread presents a flat upper surface 3 and an inclined lower surface 4, such surfaces converging to a sharp edge 5. To the upper end ofthe tube 1 is screwed a cap 6 of inverted truncated conical form and the least diameter of which exceeds the outside diameter of such tube 1. Said truncated conical cap has a flat upper surface 7 and is provided with an exterior spiral thread S which is similar in form to taat on the tube 1. A. tube 9, which is of less diameter than the tube 1, has its lower Specication of Letters Patent.

portion screw threaded, asy at 10, and is screwed in and extends' through a. central opening inthe upper portionof the cap, opposite the upper end of the tube 1. To, the

-lower end of said lube 1 is screwed a tee 11, 55

the horizontal :arm 12 of which is of reduced diameter adapted for the attachment of a pipe 13 which leads from the exhaust of an explosion engine, indicated at 14. The' vertical arnl o? the. said tee is of greater dialneter than the tube 1, and the lowerfend of such vertical erm of the tee is closed a screw plug 15 which is removable therefr n1 and which whenremovcd enables access to be obtained to the interiorof the tube 1. Suclr tube 1 has its major portion disposed in ai' extended through a carbureting or gas airA air mixing conduitI 1G which is here shown as a tube of greater diameter than the heat ing and generating tube 1.

A cross coupling 17 is screwed to the lower end of the tubs-A 1G, and its horizontal arm has its ends 'provided ith removable screw plugs 1S, 19. Such screw plugl 1S has a threaded 'Y opening in which is screwed the upper end of a feed pipe 20, which in practice. leads to the engine 14 to supply the explosive mixture of gas and air to such engine and is provided with an air v sre 21 to enable such explosive t mixture to be diluted with air in any Suitable S0` proportion, amor-ding to the extent to which such valve is open. In the lower side of the cross coupling 1T is an opening through which the lower port-.ion of the heating and gener` ating tube or conduit 1 extends, and a )ack- S5.

ing chamber :F2 is also formed on the lower side of such cross coupling for the reception of packing-213 :and a gland 24,wl1ich gland is screwed in sut-h packing chamber and compresses the ps sing 23 so as to compress the 90 latter around the lower portion of the heating and generatirgY ubel to effect a. perfect-l tight joint between such tube 1 and sue 1 cross cou ling- A similarcross coupling 25 is screwe( te i se upper end of the carburet- Ving or gas and air mixing conduit or tube 16.

whichthe tube 26 is connected. per port-ion of such cross coupling 1s a feed leading to and communicating with the gas and an' inixingor carbureting conduit 1P. Said tube 16 is provided at its'outer end with aI reducer cap 27 to which is connectedan airintake valve 2S. 'I he cap `6 isin the lower portion -of the upper cross coupling 25. A plug 29 is screwed in the end'of the horizont-al arm of such cross coupling oppositeY that to In the u peup or `pan 8O 'which is serewei on the tube 9 andis provided with small openings 31 in the bottom to permit keroscne,'crude oil, or other suitable liquid hydrocarbon to pass from such cup tothe exterior of the tube 9. A fuel feeding pipe 32 passes through the upper side of the cross coupling 25 to discharge oil o1` other suitable liquid hydrocarbon into the said cup 30 and is provided with a fuel feed regulating valve 33 which is preferably a needle valve. An overflow p1pe34 of suitable diameter leadsfrom the lower cross coupling 17 to prevent oil or other liquid hydrocarbon from accumulating-in the carbureting or gas and air mixing conduit formed by the pipes 16 and the couplings which are connected thereto. l,

'lhe operation of the inventionis as follows: Assuming that the engine is `in operation and the exhaust is being discharged therefrom through the heating andy gas gcnerating conduit consisting of the tubes 1, 9 and the cap 6, such conduit will become highly heated by the spent gases and other )roduct-s of combustion inthe engine. The iuel feed tube 32 being opened tothe required extent by the regulating valve 31, kerosene oil, crude oil, or other suitable liquid hydrocarbon will be sup plied to the cup 30 and will pass from such cup through the openings 31 to the exterior of the tube 9 and vfrom thence to the outer surface of the ca i 6 will pass down the spiral threads on such cap and on the tube l, and hence will be disposed in a. film which, as it passes down and around the tube 1, will be constantly exposed to the air drawn through the valve 2S, tube 26, coupling 25, 17, tube 16 and tube 2() by the suction of the engine. It will bc understood that the tube 1, being as before stated highly heated by the products, will heat sucliair by radiation and furthermore thatl owing to. the heated condition of such conduit 1 the film of liquid hydrocarbon on the coiled exterior` thread thereofwill be converted into gas,

to the engine by the generator. Such mixture of gas and Iair may be diluted to any required or desirable extent by appropriately open ingl the valve 2 1 lliurthermore, the Volume of air admitted to the generator may be cont rolled byappropriately opening the valve 2S. and 26 of the cross couplings 17 and 25 are such as to cause the carlnireting or gas and air mixing chamber or conduit to also4 constitute a gas reservoir which, after the engine has been stopped and the valves 33, 28 and 21 have been closed, will contain a sullicient quantity of gas or comminglcd gas and air-to restart the engine. By first removing the plug 15 and applying a suitable torch to the opening formed by the removal of such plug at the bottom of the heating and generating conduit the latter may be heated to the rcuired extent to sta-rt the engine in the event t iat there is no store of gas in the carbureting conduit.

A gas generator embodying our invention may be readily manufactured at a comparatively small cost. and lmay be constructed almost wholly of ordina-ry plumbers supplies which may be readily purchased at reasonable cost in the open market.

-In practice the carbnreting conduit will preferably be provided with a suitable asbestos or other packing to prevent loss of heat b v radiation.

Having thus described the invention, what is claimed as new, isz- 1. A gas generator comprising an upright outer tube, a crois coupling at the upper end thereof having a closure at one end, a tube attached to the opposite end of said cross coupling, and having a. closure and a valve at its outer end. a cross cou )ling at the lever end of said upright tube, raving closures at its ends, and a tube leading from one of said closures; an upright tube of less diameter than and emending through the outer tube and the cross couplings and forming a duct for a heating medium, and means to apply a liquid hydrocarbon to the exterior of that portion of the said inner tube within the outer ,the lower end of said upright tube having closures at its ends, and a tube leading from one of said closures; an upright tube of less diameter than and extending through the upper tube and the lower cross coupling and )rovided at its lower cad with a closure, said inner upright tube having an exterior spiral thread, an inverted conical cap at the upper end of said inner tube in said upper cross The length and diameter of the tubes 16 ,Y
